neutrino inportance

[Ezekiel.]

Is there anything else that the neutron does other than saveing the conservation laws. i mean there has to be something else the neutron plays a part of in the universe.

[chroot]

What does the bottom quark do for the universe? This is not a sensible question.

Neutron or neutrino? The neutron is responsible for stabilizing atoms to allow multiproton atoms to form, whereas neutrinos teach us astronomy :smile: - actually they might be responsible for some more CP violation, but we don't know yet since it's so hard to make any measurements with them.

Well, neutrinos were at first brought into physics just to save conservation laws of energy and momentum in beta decays. But later they have also been detected, so I do not see a point of this discussion? O_o

Well, another thing that neutrinoes could partly solve, is the problem of dark matter. If they had a tiny mass (as expected nowadays) they could be the hot dark matter. Cold dark matter is still a big question, as well as origin of neutrino masses. :|
